TECHNICAL DATASHEET#TD1516AX 3 AMP SOLENOID DRIVER User Selectable V or ma Input Bipolar or Unipolar 0-3A Output Adjustable Dither and PWM Frequency PCB Board or Packaged in Metal Housing P/N: RSD-x-3A-y Where x = PCB card style SMB metal box style with 1.5m cable y = 00 metal box style with strain reliefs 01 3 connectors Description: The 3 Amp Solenoid Driver simplifies control of proportional solenoids by supplying a current proportional to a user selectable input control. It is suited for industrial applications interfacing with a PLC. The available inputs include: 0-2.5V, 0 to +/- 2.5V, 0-5V, 0 to +/-5 V, 0-10V, 0 to +/-10V, 0 to +/-20V, 4-20 ma, and 0-20 ma. The controller accepts power supply voltages from 8 to 28 VDC. This linear solenoid driver utilizes high frequency switching output (PWM) to provide a DC current output. Output is user selectable as 0 to 3 Amps or 0 to +/- 3 Amps. A current sensing circuit maintains output current regardless of changes in input voltage and coil resistance. The user can adjust PWM frequency, maximum current, minimum current, a superimposed dither frequency and amplitude using single turn trim potentiometers. A sine, square or triangle dither waveform is user selectable. An auxiliary output permits monitoring of current output with a voltmeter with a scale of +/-1V/1A. The unit is available as a stand alone PCB Board or as a Packaged Driver enclosed in an IP67 rated metal housing with cable or strain reliefs. It is designed for mounting close to the valve. Other versions are available with a 2A maximum current output including a remote mount driver with filter and various DIN 43650 coil mount models.

Operating the driver with a supply voltage lower than the solenoid rated voltage may result in reduced maximum current output. Note 2: The coil should have no polarity or protection diodes for proper operation of the device. Note 3: The maximum current output of the driver should not exceed the current rating of the solenoid coil. Adjustments All potentiometers are multi-turn.

Adjusting the minimum current will shift the maximum current setting, as shown. Adjusting the maximum current (I-max.) does not affect the minimum current (I-min.) setting. Setting the Minimum Current (I-min.) The minimum current setting can be used to take into account the mechanical valve deadband and provide desired offsets from zero to allow full control within the functional range of the specific valve. Set the minimum current before setting the maximum current. Apply minimum input (in the case of 0-5V, 0 V). The factory setting for the I-min. trim pot is set at 0 Amps or midpoint. If the desired minimum current is greater than 0, adjust the trim pot clockwise (CW) until the desired current is achieved. Setting the Maximum Current (I-max.) Apply maximum control (in the case of 0-5V, 5 V). The factory setting for the I-max. trim pot is 100%. Turn the trim pot to adjust the current setting to the desired maximum. The maximum current setting is adjusted to meet the customer s working pressure or flow range to the full scale signal input range. This provides maximum control for a specific application. Mounting Instructions and Wiring Connections For PCB cards: Mounting the PCB board The board will accommodate #6 size mounting screws (not supplied). Connecting to the screw terminals on the board Reference the label (included with the board) for the pin out connections of the screw terminals. Chassis ground connections can be made to the Power terminal. Use a cable to connect to the PCB board with each wire stripped to 6.5 mm (1/4 inch) and the shield (jacket) stripped to permit splaying of the wires in the screw terminals without tension. The exposed ground shield wire should have a heat shrink placed around the wire as a precautionary measure. To connect the cable to the board, loosen each screw terminal, insert the pre-tinned wire and tighten with a jeweller s sized screwdriver. Take care to position the ground shield wire away from the PCB Board. The auxiliary output is used to allow connection of a voltmeter to indicate the level of the output current where the scale is 1V = 1 Amp. TD1516AX 5
For Packaged Drivers with cable (Metal Box): Mounting the housing Mount the housing using four #10-32 bolts or screws. Connecting the cable Connect the shielded cable to the load, power supply and input signal as follows. The drain wire from the shielded cable is connected to the particular Chassis GND for the application. The auxiliary output is used to connect to a voltmeter to indicate the level of the output current where the scale is 1V = 1 Amp. For Packaged Drivers with 3 connectors (larger Metal Box): Mounting the housing Mount the housing using four #10-32 bolts or screws. Connector Pin Out: The pin out shown below is for three male connectors mounted in the metal box. Use a shielded cable to connect to the solenoid and connect its drain wire to Pin 1 on the solenoid connector in the metal box. TD1516AX 6
